1 Claim.

The present invention relates to new and useful improvements in filling cutters for looms and has for one of its important objects to provide, in a manner as hereinafter set forth, an attachment of this character comprising a novel construction and arrangement whereby the device will function only when there are threads to be cut.

Another very important object of the invention is to provide a filling cutter of the aforementioned character which is adapted to be expeditiously installed for operation on a conventional loom without the necessity of making material structural alterations in said loom.

Other objects of the invention are to provide a filling cutter attachment for looms of the character described which will be comparatively simple in construction, strong, durable, highly efiicient and reliable in use, compact and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference. designate corresponding parts throughout the several views, and wherein:

Figure 1 is a fragmentary top plan View, partly in section, showing the replenishing end portion of a loom equipped with an attachment con- I structed in accordance with the present invention.

Figure 2 is a view in side elevation of the invention mounted on the loom, the lay and reed of said'loom being shown in cross section.

Figure 3 is a view in front elevation of the filling pusher or sweep in position on the lay.

Figure 4 is a Vertical sectional view, taken substantially on the line 44 of Figure 3.

Figure 5 is a top plan view, showing the device engaged with the outgoing filling end.

Figure 6 is a view in horizontal section, illustrating the manner in which the thread is cut.

Figure 7 is a detail view in perspective of the stationary cutting blade.

Referring now to the drawings in detail, it will be seen that the embodiment'of the invention which has been illustrated comprises what may be referred to as a bracket which is desigslot 5 accommodates a screw 6 which adjustably secures the bracket I in position on the lay 2.

The bracket I further includes a pair of apertured ears I which project forwardly from the vertical edges of the plate 4. Extending between the apertured ears 'I of the bracket I' is a metallic pin or shaft 8. Journaled for swinging movement in a vertical plane on the shaft 8 is a thread pusher or sweep 9 of suitable metal. The thread pusher 9 is of substantially the shape shown to advantage in Figure 3 of the drawings and comprises a pair of integral, apertured ears I!) which are journaled on the shaft 8 adjacent the ears 'I of the bracket I. A coil spring II is mounted on the shaft 8 and operatively engaged with the thread pusher 9 for yieldingly maintaining same in raised or operative position. As illustrated to advantage in Figure 4 of the drawings, the construction and arrangement is such that the upper portion of the bracket plate 4 limits the upward swinging movement of the thread pusher 9 under the influence of the coil spring II.

The pusher or sweep 9 further includes a vertical inner marginal portion I2 having formed in its upper end portion a notch or the like I3 for the reception of the thread to be cut for preventing said thead from slipping off the member 9.

The temple of the loom 3 is indicated at I4 and comprises a head I5. Mounted in the head I5 for engagement by the outgoing filling ends to be cut is a sharp blade I6. Referring again to Figure 1 of the drawings, the outgoing filling end is indicated at I! and the incoming end is indicated at It is thought that the manner in which the device functions will be readily apparent from a consideration of the foregoing, particularly to those skilled in the art to which the invention pertains. Briefly, when the loom has been replenished and the lay 2 recedes, the pusher 9 engages the outgoing end I! and is swung downwardly thereby against the tension of the spring II, substantially as suggested in broken lines in Figure 4 of the drawings. When the pusher 9 clears the filling end I"! said pusher is returned to its raised or operative position by the spring I I. On the next forward stroke of the lay 2 the pusher 9 engages the outgoing filling end I1 and sweeps it forwardly into engagement with the cutting edge of the stationary knife IS on the loom temple I4 for cutting said filling end II, substantially as seen in Figure 6 of the drawings. Thus, the filling end is cut cleanly at a x more than one end to be cut, and should the device fail to cut them all on the first forward stroke of the lay, the pusher or sweep 9 will continue to function until all of the ends have been cut.

It is believed that the many advantages of a filling cutter constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the device 10 is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

A filling cutter for looms comprising a bracket for mounting on the lay of the loom, said bracket including a plate having a vertical slot therein and further including apertured ears projecting forwardly from the plate, a bolt engaged in the slot for adjustably securing the bracket to the lay, and a sweep mounted for swinging movement in a vertical plane on the bracket and when, in upstanding position, engageable with an outgoing filling end to be out, a shaft extending between the ears of the bracket, apertured ears on the sweep journaled on said shaft, and

' 'acoil spring mounted on the shaft and engaged with the sweep for yieldingly maintaining said sweep in operative position.
